Lesson Summary
Students place drops of water on a sloped surface to observe the flow of water downhill. They observe how changing the size of the water beads affects the flow. They observe how increasing the slope affects the flow.
Teacher Background

- Larger amounts of water flow more quickly.
- Increasing the slope over which water flows makes it flow more quickly.
- Teacher Observations: Response Sheet—Students give advice to a family that has gone camping.
Set-up/Management Tips
